TAPE SUSPENSION on wmnow s sH-Ann THE LIKE Application filed December29,192 senaino. 329,251; v

The invention has for an object to effect improvements in the hangingof" window sash and the like by meansof metal tapes,

and particularly to enablethe embodiment of means to this end in suchmanner that the use of metal tape for this purpose may be effectedeconomically and at a cost comparing favorably with the use vof wovenfiber cord or chain'such" as haveheretofore been .7 generally used; Itis a special aim to provide a construction and arrangement adapted r toenable the hanging of a'sash on metal tape where the sash and frame arethe same as v ordinarily used with cord or chain. Particularly, it issought to, obviate the need for special tools in equippinga sash with atape suspension, utilizing the ordinary sash;

weight.

- An important "aim of the invention is to enable the use of metaltapeinsuspension of v sash upon a pulleywithfcounterweight in such manner thatdisplacement of the tape fromthe pulley willbe prevented, as well astwisting-of the tape and other derangements' obviated. A further,important object is'to minimize wear of the tape and also lessen shocksthereto incident itorabrupt stoppage movements. I

. Where the'tape is connected tothe weightit is run through the loopofthe P-shaped man'u the presentinstancethe stile has been mortised asheretofore usual for the attachment I of a simple braided fiber cord.That is to'say,

a groove 17 is formed invthe edge of the sash stile at theupper part,and a distance below 5 the groove a bored recess 18 open on thesideofthe stile is formed connected with the 'gro'o'veby a bored passage19'ofsmaller di ameter than the recess 18. The sash is hung castinghaving two cheek plates 23Qbetween whichthere is mounted the pulleywheel 24;,

lwhichjin the present instance is formed with a channelled periphery,the bottom of the channel in t'he pulley being flat, and the flanges 25thus formed at the sides being much higher than the thickness oftheta'pe which isjto be used to suspend th'esash. The plates 23amformed'integrally {with a mounting plate 26 at-rightfangles to them andof conventional-for'm, apertured' to receive fasten f5 ing screws bywhich the pulley is securedto the frame 5 20. The plates extend abovethe wheel',and engaged through the upwardly extended parts of the platesdiametrically U above the pulley there is a 'pintle' 27 on which so ap-ilotroller 28 is-mounted of a diameter to extendinto thegrooveoftheiwheel a-distance and of; a'jlength to fit'loosely between-"theflangesofthe wheel. a Overthe pulley and under the pilot roller there islaid a tape 29 ofsuitable thin 'fiex-i ible metal, the ends of the tapebeing connected respectively to the sash and to a weight 30 ofconventional form."

guard 33. Thelatteris'aJchannel-form steel in p I member bent mediallyto substantially a U- shape initially, and manually bendable further tobring its ends together so as to form a substantially pear-shaped eye.The flanges 5 34: of the guard are located at its outer sides and spacedso as to receive the tape snugly therebetween. The extremity of the tapeis next again inserted through the P-shaped tie 31 in a direction thereverse of that in which it was first inserted, close upon that part ofthe tape already engaged therein, but at the side next the stem portion35 of the tie, and the extremity of the tape on this second insertion inthe tie is allowed to project a short distance. It is then bent sharplybackward upon the overlying part of the tie. The stem part of the tie isfinally bent down upon the inturned end of the'tape so that it is heldsecurely against loosening. The manual bending of the tie upon the tapeparts will afford security, but the completed tie may be furtherflattened and secured by being squeezed in a pair of pliers, or by beingstruck by a hammer while laid on a flat surface. The tape is engagedwith the sashat 18 in any approved manner. It will. be noted that theperiphery of the pulley wheel lies with the bottom of the groove at thefront side immediately outward of the plane of the plate 26. The roller28 stops short of the bottom of the groove just suflicient to permit thetape 29 to pass thereunder as described. It nevertheless extends intothe groove a substantial distance, so that the tape is held with aconsiderable extent of flange 25 extending above and forwardly of thetape, throughout the upper part of the pulley. Owing to the rigidity ofthe tape to flexure in directions transverse to its majortransverseaxis, any tendency of the tape to'ride upon the flanges 25 is firmlyopposed as long as the tape is held under the roller 28, because thetape itself so opposes bending toward the sides of the sheave that itcannot get sufliciently out of line to ride on the flanges 25. 1 Iclaim:

. A sash suspension comprising a case adapted to be mounted in a windowframe, and including a vertical face plate, cheek plates extendedinwardly therefrom, a wheel mounted between the cheek plates having aflat-bottomed groove and having its periphery closely ad] acent andoutward of the plane of said plate at'the front side of the roller, anda pilot roller of cylindrical form revolubly mounted between the saidcheek'plates at the upper side of the wheel, and set in the groove asubstantial distance adapted to lie close to a tape in the groove, andclose tov the sides of the groove, and a tape closely confined inthebottom of the groove under the roll r.

In testimony whereof I aflix' my signature.
